Fitz, a takedown .30-40 Hi-wall strikes me as an eminently practical hunting rifle. Not to mention an elegant solution to the deer/elk problem. Or is the Krag one of those "crazy modern calibers" that makes the wrong color of smoke and not enough of it? At least it's got a rim....

(Maybe you should rebore it to .40-70 for the sake of purism and auld lang syne....I call it the Garbe solution. Or just make a .40-70 barrel for those blackpowder moods that can come over one.)
